If there are any references right here or in your theme that you just don’t perceive, you'll be able to take a look at the official WordPress Settings Reference.
Some components, like colours and font households, have slugs, like this:

{

"color": "#ffffff",
"name": "White"
},
These will come in handy for the styles section later on to make presets, which we will explain in the next part.
Styles

Here, you can apply the customization settings to the entire website or at a block level using presets.
Let’s check out the example below:
{
"settings": {
// Existing settings from the previous example
},
"styles": {
"color": {
"background": "var(--wp--preset--color--base)",
"text": "var(--wp--preset--color--contrast)"
},
"elements": {
"link": {
"color": {
"text": "var(--wp--preset--color--accent-2)"

"lineHeight": "1.2",
"marginBottom": "1rem"
},
"h2": {
"fontSize": "var(--wp--preset--font-size--x-large)",
"lineHeight": "1.2",
"marginBottom": "1rem"
},
"h3": {
"fontSize": "var(--wp--preset--font-size--large)",
"lineHeight": "1.2",
"marginBottom": "1rem"
}
}
}
}
As you can tell, there is this line of code appearing throughout this snippet: var(--wp--preset--xxx) . These are presets, which are shortcuts in the styles section that refer back to the values defined in the settings section.
For example, consider {"slug": "base", "color": "#ffffff", "name": "White"} in the settings section. Here, "base" is the slug, and the corresponding preset for this color is var(--wp--preset--color--base) .
Therefore, the code "color": {"background": "var(--wp--preset--color--base)" in styles says that the background color of this theme is white.
Custom Templates
Block theme developers can create predefined layouts for custom pages, posts, or post types for users to use.
For example, the Twenty Twenty-Four theme has several custom templates defined in the theme.json file: Page No Title, Page With Sidebar, Page with wide Image, and Single with Sidebar.
You can use any of these to create your content.
],
"customTemplates": [
{
"name": "page-no-title",
"postTypes": ["page"],
"title": "Page No Title"
},
{
"name": "page-with-sidebar",
"postTypes": ["page"],
"title": "Page With Sidebar"
},
{
"name": "page-wide",
"postTypes": ["page"],
"title": "Page with wide Image"
},
{
"name": "single-with-sidebar",
"postTypes": ["post"],
"title": "Single with Sidebar"

Nevertheless, the precise look and performance of the customized templates are outlined in separate template recordsdata contained in the theme folder.

Template Elements
Template elements are reusable areas you'll be able to apply throughout your customized templates. These are components like headers, footers, sidebars, and so on.
Right here’s what these template elements appear to be registered in theme.json:
"templateParts": [
{
"area": "header",
"name": "header",
"title": "Header"
},
{
"area": "footer",
"name": "footer",
"title": "Footer"
},
{
"area": "sidebar", // Removed "uncategorized"
"name": "sidebar",
"title": "Sidebar"
},
{
"area": "post-meta", // Removed "uncategorized"
"name": "post-meta",
"title": "Post Meta"
}
]
Like customized templates, the theme.json file solely references the templates.
Their precise look is outlined in their very own template half recordsdata in the elements folder.
